hard to guess the problem.

1. delete in your browser all cookies for your site and try to login

2. in punBB config.php set $cookie_domain = ''; to $cookie_domain = 'yourdomain.com';
and check (try also with deleted cookies)

3. if it still doesn't work then it must have problem with this (jl-punbb.php plugin):

setcookie($cookie_name, serialize(array($user->id, md5($cookie_seed.sha1($user_pass)))),  time() + 31536000, $cookie_path.'; HttpOnly', $cookie_domain, $cookie_secure);

it may need some hacking then like: $cookie_path.'; HttpOnly' to $cookie_path

Thanks for the very fast answer!

I tryed everything but it doesn't work..
But if i dont use the login.php modification, only the normal punbb login file, everything ok, i log in with my WP username and password to the forum.
I use Wp 2.2.2, this Wp version dont possible problem?

I first want to say thanks for this great plugin!
My english is terrible, im sorry for this,  but i hope you understand my problem.
I follow your instruction step by step, but the modification dont work for me.
The WP userlist transferring perfectly to the punbb, the WP login working good, but the forum always write this: You are not logged in. I try login with different user, but it doesn't work, i can't login to the forum!
Thanks for your help..

I used: WP: 2.2.2 | punBB: 1.2.15
WP address form: thisismysite.yyyyyyyy.xx
PunBB address: thisismysite.yyyyyyyy.xx/forum

Details:
define('PUNPATH', '../forum'); // path to punbb folder
define('PUNPREFIX', 'pbb_'); // punBB table prefix
header('Location: thisismysite.yyyyyyyy.xx/wp-login.php?action=register'); etc etc etc
